BY a, WQ FM Patented Feb. 24, 1953 UNITED STATES PATENT OFFICE PAPEROUTTER; FOR PAPER Mm. DRYING ROLLERS John "c. Nix, III, Tuscaloosa, Ala. Application February 4, 1948, Serial No. 6,327 9 dinin (or. 3445) The present invention relates to new and useful improvements in paper cutters and-more particularly to paper'cutters for use in cutting broken or torn paper from the drying rollers 'of paper mills.

Durin the manufacture of paper in paper mills the paper is run over a series of driers or rollers for the purpose of drying the paper. When the continuous paper sheet is broken or tom the loose paper generally wraps itself around one or more of the rollers or driers and must be removed before the paper is again fed to the rollers.

The drying rollers or cylinders are usually mounted in a triangular arrangement and not always accessible for removing the broken or torn paper therefrom. Accordingly it is an object of the present invention to provide a paper cutter which may be moved longitudinally between the rollers and embodying a rotatable cutter which may be positioned to travel longitudinally along any one of the rollers to cut the paper therefrom to facilitate removal of the torn paper. I

A further object of the invention is to provide a device of this character of "simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same isintended. A

e Other objects and advantages reside in the details of constructionand operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, andin which: i v

Figure 1 is an end 'lev'ational view of the cutter; A H

Figure 2 is a si'r'nilar new showing the cutter in use;

Figure 3 is an enlarged view in elevation of one of the guide rollers and mounting therefor;

Figure 4 is a similar view of the rotatable cutter and mounting therefor;

Figure 5 is a longitudinal sectional view, and

Figure 6 is a transverse sectional View taken substantially on a line 6-6 of Figure 5.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates a flat substantially triangular shaped body having a pair of hollow arms 6 projecting from two of the corners of the body and a relatively short hollow arm I projecting from the third corner of the body,

the arms extending radially from an opening 8 .plunger It) also forming awheel mounting. The

outer ends of the plungers Bare bifurcated as shown at ll and provided with transverse pinsl2 removably secured in position by cotter keys or the like I 3 'and on whichaguide roller I4 is journalled. The outer endof the wheel mounting Ill is likewise bifurcated as shown at I5 and provided with a transverse pin I6 removably secured inposition by cotter keysll and on which a rotatable cutter I8 is joumalled, The inner ends of theplungers areformed with threads 93.

The outer portions of the wheel mountings 9 and lo are reduced in diameter to provide a shoulder l9 against which the inner end of a coil spring 20 is positioned, the spring being held under tension in the hollow arm by a hollow plug 2! threaded in the outer endnof the arm and through which the wheel: mounting isslidable.

The inner ends of the wheel mountings 9 and lll'project into the central opening 8 inthe body for engagement by a tapered feed screw 22 slidable in the opening.

The ends of thefeed screw 22 project outwardly from the opposite sides of the body 5 and are smooth for sliding movement in front and rear guides 23 and '24 supported respectively forwardly and reartvardly of the body 5 by brackets 25 and 26.

A guide roller 2'! is supported under the bracket 25 by 'a downwardly extending arm 28.

In the operation of the device a group of paper drying rollers or cylinders is designated at 29, 30 and 3|, the cylinder or roller 29 being positioned under the cylinders or rollers 30 and 3% as shown in Figure? ofthedrarwings.

U The paper cutter'is "moved longitudinally betweenthe rollers 29, 3B and 3| with the guide rollers l4 carried by two of the arms 6 or I traveling along two of the drying rollers and the rotating cutter l8 traveling along the third drying roller to cut the paper therefrom.

The springs 20 retract the wheel mountings; 9 and Ill and the feed screw 22 projects the wheel mountings to adjust the guide rollers l4 and cutter 18 into an effective cutting position.

The guide rollers l4 and cutter l8 may be interchangeably mounted on the wheel mountings 9 and H] to position the cutter for cutting the paper from either of the drying rollers 29. 301

rollers.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of they construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a. preferred embodiment of the invention the same is susceptible to certain changes fully compre- V hended by the spirit of the invention as herein invention, what is rollers, spring means retracting the-mountings,

and wheels journalled at the outer ends of the mountings, at least one-of the wheels constituting a cutter. v

2. A paper cutter comprising a body having a plurality of hollow arms projecting radially therefrom, a wheel mounting slidable in each arm, means Working in the body at the inner ends of the mountings for projecting the mountings, spring means retracting the mountings, and wheels 'journalled at the outer ends of the mountings and adapted to travel longitudinally of and with the body centered between 'a group of triangularly arranged paper drying rollers, at .least one of the wheels constituting a cutter.

3. A paper cuttercomprising a carriage adapted to travel longitudinally between a group of triangularly arranged paper drying rollers, said carriage including a plurality of arms projecting radially from the longitudinal axis of the carriage, a cutter carried at the outer end of at least one of the arms for cuttingpaper from one of the rollers, wheels mounted atthe outer ends of the remaining arms to travel along the surface of the remaining rollers: to center the carriage between the rollers and a handle on the carriage to move the carriage back and forth along the 4. A paper cutter comprising a manually manipulated carriage adapted to travel longitudinal- 1y between a group of triangularly arranged paper drying rollers, said carriage including a plurality of arms projecting radially from the longitudinal axis of the carriage, a rotary cutter mounted at the outer end of at least one of the arms for cutting paper from one of the rollers, and wheels mounted at the outer ends of the remaining arms to travel along the surface of the remaining rollers to center the carriage between the rollers.

5. A paper cutter comprising a manually manipulated carriage adapted to travel longitudinally between a group of triangularly arranged paper drying rollers, said carriage including a plurality of arms projecting radially from the longitudinal axis of the carriage, a rotary cutter mounted at the outerend of at least one of the arms for cutting paper from one of the rollers, wheels mounted at the outer ends of the remaining arms totravel along the surface of the remaining rollers to center the carriage between the rollers, and means carried by the carriage for radially adjusting the cutter and wheels on the arms.
